Twelve deer occupy a six square foot area of land what is the density of the area ?

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

the answer is b.6
